Agricultural Business-critical App for Farmers

This project involved developing, maintaining, and supporting an agricultural business-critical application called CargillAg for farmers. It allows external and Cargill's internal customers to view market prices of different commodities such as barley, soybean, and corn. It also shows accounts, deliveries, settlements, and payment information based on location.

To develop this app, we used Spring Boot with Java on the back end and HTML5, CSS3, and JavaScript with React on the front end. We also leveraged Adobe Experience Manager (AEM) for content management, PostgreSQL as the cloud database, and Datadog for logging and monitoring. I acted as the technical lead, assisting functional team members in gathering requirements from the business and converting them to technical requirements. In addition, I assisted multiple front-end and back-end developers during the app's development.
